Abstract
Multifocal lens provided with a reading part disposed near the bottom part and another lens, such as a distance lens, near the top part. According to the invention, the outer limit of the reading part lies on or within the (outer) radius RV of the remaining part of the lens. This means that no thickening is needed for the reading part, and a particularly gradual transition between reading and distance part can be provided.
